Time signal apparatus. Patented in the German Empire on June 15, 1904.

Signal devices attached to clocks are known, some of which are current closers by a clock hand, partly by driving rods with gears from the pointer shaft be moved. By the current closers used in these signaling devices and by the way of their attachment and movement could use one electric current to a certain

ίο a bell will be given at the time of day. So far, however, it has been possible to use these devices without the aid of a circuit breaker not be achieved that when the same time returns after 12, 24, 36 ...

Hours the power supply was soon prevented, soon allowed.

The present invention now features a signaling device attached to a watch whose .stromschler is achieved that at a desired time there is a short circuit, but that after 12, 24, 36 ... hours each time the same hour returns soon there will be a short circuit and will soon be avoided.

On the accompanying drawing that shows the time signal apparatus Fig. Ι the overall view of the subject of the invention, Fig. 2 one of the used in it Current closer.

The essential components of the time signal apparatus are:

1. A lever a (pointer) rotatable about a shaft c.

2. Current circuit wheels, which are attached in any number at the same distance from the shaft c.

Each power transmission wheel is composed of the following individual parts: From an electrically conductive angle, on which a likewise conductive, metal gear wheel is attached so that it can rotate around the axis /. On the axis / of the gear e, h with their surface an insulating washer lying parallel to the axis · ■ contact pins k fixed so that the contact pins k with the gears e and the metal angle b in conductive connection stand-on of the insulating h is a metal spring m attached to angle b , which is isolated from angle b by an insulating plate r. ■ _

The terminal screws ρ and q bring the device into an electrical circuit s , in which bells t are switched.

The mode of action is therefore as follows:

The length of the lever or pointer α is dimensioned so that it moves the gear e in jerks, one tooth at a time, with each full revolution. Simultaneously with the gear wheel e , the insulating disk h with the contact pins k located in it is also moved jerkily forwards, while at the same time the contact spring m grinds on the insulating disk h. Whenever a contact pin k comes into contact with the contact spring m during this jerky forward movement of the current circuit wheels, the electrical circuit s is closed by the components p, m, k, e, b ' and q and the bell is activated. If, on the other hand, the line (arc) of the insulating washer h is covered by the contact spring, m

no contact pin, so the current circuit is prevented.

The apparatus can be attached to the face of a clock so that the circuit wheels by a pointer of the clock, which is also a rotatable lever, for each Rotation of the same by one tooth each jerky 'are moved forward'. Since the Current circuit wheels at any point

ίο the circumference of the dial fixed or reduced can be slidably attached, so you can reach a signal at any time. It should now z. B. the task can be put on the machine, repeated weekly on the individual days of the week, without the circuit being switched off at certain times, or the circuit wheels adjusted or postponed, the following times should be announced by the bell:

Sunday: 7 a.m. Monday: 12 noon; Tuesday: I ¹ Z ₂ p.m.; Wednesday: 12 noon and 12 noon; Thursday: 1Y ₂ am: Friday: 12 noon; Saturday: 7 p.m.

To make this possible, one attaches a 14-tooth circuit wheel, corresponding to the two times seven periods of 12 hours or two times seven revolutions of the hour hand by means of the angle b on the digits XII and VII, a third one in the middle between the digits I and II, namely at such a distance from the pointer shaft c- that the small clock hand moves each of the three current circuit wheels by one tooth for a single revolution. Then the eight contact pins required for the eight times to be reported are inserted into the insulating washers h in a conductive connection with the gears e as follows: The circumference of the three insulating washers h is in this case divided into 14 equal parts (arcs), with the one for Saturday at 12 o'clock in the evening to 12 noon on Sunday, this part is designated as the first. You now set for the days on which the bell should ring at 12 noon, i.e. Monday (noon), Wednesday (noon and night) and Friday (night),. One contact pin each in the 3rd, 7th, 8th and 12th part of the circumference of the insulating washer h of the short circuit wheel attached to number XII, also for the days on which the _{bell should ring at 1Y 2} o'clock, Tuesday (afternoon) and Thursday (in the morning), in the 6th and 9th arch of the insulating washer of the circuit wheel attached in the middle between numbers Ί and II and for Sunday (morning) and Saturday (afternoon), where the signal should sound at 7 a.m., in the 1. and 14th arch of the insulating washer of the circuit wheel attached via number VII. The circuit-breaker wheels are then adjusted on Saturday evening before midnight in such a way that, when they move forward for the first time, the small pointer shows the i. Arch each of the three insulating washers with the contact pin slides under the contact springs. With every further rotation of the wheels after 12, 24, 36 ... hours, the 2nd, 3rd, 4th arcs of the insulating washers pass under the contact springs, so that at the end of the week, when the wheels are switched on the 14th, the 14th Arch of the insulating washers is coated by the contact springs. Now, however, there is a contact pin each in the 3rd, 7th, 8th and 12th arch of the circuit wheel attached via XII, so that the latter at the 3rd, 7th, 8th and 12th rotation of the small hand, therefore on Monday and Wednesday 12 noon and Wednesday and Friday 12 noon at midnight slide past under the contact spring and at this time the power supply and the bell signal are brought about, while at the same time of day or night on other days due to absence In the current connection wheel attached between I and II there is a contact pin in the 6th and 9th arch of the insulating washer, so that for the same reason as before with the 6th and 9th circuit, as o A signal is given on Tuesday ₁ and 2 a.m. and Thursday ₁ and 2 a.m., while otherwise the signals are not given during the whole week at _{1 and 2 a.m.} The circuit wheel attached to number VII causes the contact pins inserted in the 1st and 14th arcs of its insulating washer to ring the bell on the 1st and 14th switching by the small pointer, i.e. on Sunday 7 a.m. and Saturday 7 a.m., while the rest of the time The occurrence of the time 7 o'clock twelve times in the course of the week is prevented due to the lack of the necessary contact pins.

It can therefore be seen that during the week the required bell signals only on Sunday: 7 a.m., Monday: 12 noon, Tuesday: _{1 and 2} p.m., Wednesday at 12 noon and 12 p.m., Thursday: _{1 and 2} a.m., Friday: 12:00 midnight and Saturday: 7:00 pm from the clock means of the Läutewerkes be given.
